Rust wants parallel LLVM, because Rust has larger compilation unit.
- azakai 4y agoInteresting. That might be very specific to Rust, though. In that case, LLVM might not be the optimal backend for rustc. But this isn't an issue for most LLVM languages, which either assume parallelism in the build system, or they get enough benefit from ThinLTO (which is the parallelism LLVM does support at the link stage).
